Low Pressure Drop Swing Non-Return Damper Reliable Backflow Prevention For HVAC Systems


1. Description:


This damper is installed on the supply and return air ducts of ventilation and air conditioning systems, usually in an open state. In case of fire, it closes when the smoke temperature inside the duct reaches 70 ℃ and can meet the requirements of smoke leakage and fire resistance integrity for a certain period of time, serving as a smoke and fire barrier. The first version of the fire damper consists of components such as the valve body, blades, actuator, and temperature sensor.
